Parasites cause eosinophilic pneumonia in three different ways. Parasites can either invade the lungs, live in the lungs as part of their life cycle, or be spread to the lungs by the bloodstream. Eosinophils then migrate to the lungs in order to fight the parasites, and cause eosinophilic pneumonia when they release their contents.
According to Hopkin, the author of a 2009 Parasite Immunology article on asthma and parasitic worms, other immunoregulatory mechanisms are also activated, including Mast cells, eosinophils, and cytokines that invoke a strong immunoglobulin E (IgE) response. [12]
Cats do not play a role in the spread of trichinosis because trichinae are rare in them and cats are not normally eaten by humans. The cat liver fluke can rarely cause disease in children if they swallow infected fleas, usually accidentally (→ dipylidiasis). Here, humans, like cats, act as the final host; direct infection from a cat is not ...
Angiostrongylus cantonensis is a nematode (roundworm) parasite that causes angiostrongyliasis, an infection that is the most common cause of eosinophilic meningitis in Southeast Asia and the Pacific Basin. [3] The nematode commonly resides in the pulmonary arteries of rats, giving it the common name rat lungworm. [4]
Some cases with multiple pairs of worms have reported low eosinophil levels, while other cases with a single pair had very high eosinophil counts. Such variation may be due to the lack of host tissue invasion by the parasite, since M. laryngeus attaches to the mucosal epithelium in the tracheolaryngeal region. [ 2 ]
Toxocara cati, also known as the feline roundworm, is a parasite of cats and other felids. It is one of the most common nematodes of cats, infecting both wild and domestic felids worldwide. Adult worms are localised in the gut of the host. In adult cats, the infection – which is called toxocariasis – is usually asymptomatic. However ...
Originating in Persia (modern-day Iran), Persians are one of the oldest and most recognizable cat breeds. They enjoy a life expectancy of 11 years. However, due to their distinct features, they ...
Feline diseases are often opportunistic and tend to be more serious in cats that already have concurrent sicknesses. Some of these can be treated and the animal can have a complete recovery. Others, like viral diseases, are more difficult to treat and cannot be treated with antibiotics, which are not effective against viruses.
